Boundary without keeping used geometry

[clemson77on]

Is there a setting that will erase the lines used to make a polyline with th boundary command? Example: I have 4 lines that create a square. I use the boundary command to create polyline. Now I have a square polyline on top of the 4 lines. I then have to manually erase the 4 lines.

If the end of a line coincides with the beginning of another, you can use a command PL-CSE

pltools.lsp

Create layer for BOUNDRY;

Create layer for PLINE;

Draw boundry on BOUNDRY layer, and change to layer PLINE and draw pline. 

Change to BOUNDRY layer and FREEZE PLINE layer. Erase Boundry geometry.

UnFreeze PLINE layer. 

Job done.

Like jagwin, make boundary get all the vertices co-ords, turn off boundary,  use ssget "f" co-ords then erase, turn boundary back on. A word of caution the erase is brutal.
